AI-generated Abstract

This study explores how geogenic and anthropogenic sources affect the oral bioaccessibility of potentially toxic elements (PTEs) in topsoils across Belfast, Northern Ireland. Elevated concentrations of elements such as Ni, Cr, V, As, Pb, Cu, and Zn—linked to historical land use—present risks to human health; however, bioaccessibility testing reveals that not all contaminants are available for absorption. Findings indicate that historical development zones correlate with higher bioaccessibility for certain PTEs, while geogenic factors can reduce bioaccessibility for others, underscoring the importance of understanding contaminant sources in environmental health assessments.
